Ingredients

Here’s what you’ll need to whip up these amazing bars, plus a few notes to help you get that perfect batch every time:

• Egg: Acts as the glue, holding everything together for bars that slice cleanly.
  No egg? You can skip it; the bars may be a tad more crumbly, but still delicious.
• Vanilla Extract: Divided between the oat mixture and berries for a double dose of warm, inviting flavor. Don’t skip it!
• Butter: Melted, because it keeps the process simple and helps with that irresistible golden top.
• Maple Syrup: Naturally sweetens the bars and the berry filling, with a taste that’s so much more interesting than plain white sugar. Adjust for more sweetness if serving as dessert.
• Oat Flour: Gives structure and a soft bite without any gluten. If you don’t have oat flour, you can make your own by blending rolled oats until fine.
• Rolled Oats: Adds delightful chew and heartiness. Old-fashioned oats work best here; quick oats will yield a different texture.
• Baking Powder: For a little lift.
• Sea Salt: Just a pinch transforms the whole bar—never skip salt in your baking.
• Fresh Raspberries: The star of the show. Their bright, juicy flavor really shines, especially when they bake and go a bit jammy.
• Tapioca Starch: Thickens up the berry layer, keeping it from getting soggy. Cornstarch works too if that’s what you have.

Tip: If you want to keep the sugar ultra-low, the recipe as written is perfect. For a dessert version, feel free to up the maple syrup in the filling.

Variations

• Vegan-Friendly: Omit the egg and use a plant-based butter or coconut oil. The bars will be a bit softer and crumbly, but just as tasty.
• Add Nuts: Mix in a handful of chopped almonds, pecans, or walnuts with the oat mixture for extra crunch.
• Berry Swap: Use blackberries, blueberries, or even a mixture—just be mindful of juiciness, as some berries let out more liquid.
• Chocolate Drizzle: Want a treat? Melt a little dark chocolate and zigzag it over the cooled bars.
• Coconut Twist: Stir a few tablespoons of unsweetened shredded coconut into the oat mixture for a subtle tropical note.

How to Make Raspberry Oat Breakfast Bars

Step 1: Prep Your Pan

Preheat the oven to 350°F. Line an 8″x8″ baking dish with parchment paper, leaving enough hanging over the side for an easy lift later. This small step ensures your bars come out perfectly, every time.

Step 2: Make the Crumble Mixture

In a large bowl, whisk together the egg, half of the vanilla extract, melted butter, and most of the maple syrup. Add the oat flour, oats, baking powder, and salt. Mix until it forms a wet, crumbly dough—don’t overmix.

Step 3: Form the Bottom Layer

Press about two-thirds of the oat mixture into your lined pan, using your hands or a spatula to smooth it out evenly. This forms the “crust” and base for the fruit.

Step 4: Prepare the Raspberry Filling

In a small bowl, toss together the raspberries and tapioca starch until coated. Add in the remaining vanilla and a bit more maple syrup, tossing and gently mashing some raspberries as you go. This creates a juicy, just-thick-enough filling.

Step 5: Assemble the Bars

Spread that gorgeous raspberry mixture evenly over the oat base, juices and all. Sprinkle the remaining oat mixture over the top—no need to be perfect, a rustic crumble is what you’re after.

Step 6: Bake and Cool

Bake for about 30 minutes, or until the topping is golden and the berries bubbly. Let the bars cool in the pan on a wire rack before slicing. Patience pays off here—it makes clean squares possible!

How to Serve

There’s more than one way to enjoy these Raspberry Oat Breakfast Bars:

• For Breakfast: Perfect plain, warmed or chilled, and paired with a cup of coffee or hot tea. Add a dollop of Greek yogurt for something extra special.
• Afternoon Snack: Great with a cold glass of milk or non-dairy milk if you prefer.
• On-the-Go: Wrap up a bar for a satisfying energy boost at work or in the lunchbox.
• Dessert: For a treat, top with a small scoop of vanilla ice cream, whipped cream, or a chocolate drizzle.

Make Ahead and Storage

Storing Leftovers

These bars are best the first day, but they keep well! Leave them at room temperature (covered) for up to 24 hours. After that, store in the refrigerator for up to 3 days to keep them fresh and firm.

Freezing

Let bars cool completely, then wrap tightly in plastic wrap and freeze in a zip-top bag or airtight container for up to 1 month. Pull out a bar and let it thaw at room temperature or microwave for a few seconds when you need one.

Reheating

Enjoy straight from the fridge, or microwave individual bars for 10-15 seconds if you like them warm, and the raspberry center turns wonderfully jammy.
